15 Things That Pose a Threat To Hedgehogs

Have You Wonder What Threats Hedgehogs Face Everyday?

The hedgehog population has continually declined throughout the years: from about 30 million in the 1950s to 1.5 million in the 1990s, down to less than 1 million today.

But, what are the causes that led to the decrease in the hedgehog population? Here are 15 threats to their survival, as well as simple tips that you can do to help arrest their declining numbers.


Roads and Vehicles

Every year, 50,000 to 100,000 hedgehogs are killed by vehicles, either on highways or local streets.


The most common victims are males searching for mates and youngsters looking for food.


It is inevitable that vehicles and hedgehogs will cross paths because roads are located in their natural territories.

So, if you know that you live in an area where they could be present, slow down at night when they are more active.


Man-made Barriers

Artificial barriers such as walls can prevent access to some regions of the hedgehogs’ territory, which means they have to look further to find food.


Metal grills and wire fences are also dangerous because they can get stuck in them and get injured.


It is not a good idea to install low-level barbed wire as this can trap and kill hedgehogs.


Natural Predators

Badgers and foxes are usually found on the same territories as that hedgehogs and are their primary natural predators.

Smaller hoglets are also vulnerable to weasels, ferrets, and rats. If you want to feed hedgehogs, avoid leaving the food outside a feeding station because this also attracts other animals like foxes.


Other Pets

Adult cats may not be able to harm adult hedgehogs, but they are undoubtedly able to kill smaller hoglets.

On the other hand, adult dogs can easily maul hedgehogs, so be wary of behavior that may indicate that your pet is chasing or attacking a hedgehog.



Wood piles attract hedgehogs looking for a place to settle during cold weather.

This natural behavior can seriously injure or kill the hedgehog when the fire is lit, so check the wood pile for disturbances with a torchlight, move the sticks around, and look inside by lifting the base with a long post.


Compost Heaps

Hedgehogs like to nest on a warm compost heap or a leaf pile, and they may get stabbed when the pile is turned or mixed with a garden fork, so check the pile before moving it.

You may not be able to handle the hedgehog but once disturbed, it will try to move away.


Garden Trimmers and Lawn Mowers

Hedgehogs will rest in tall grass or hide in them.

A sleeping hedgehog may be woken by the sound of the trimmer or mower and will run away, but a sick or injured hedgehog may not.

So again, make sure to check the area before you begin to trim.


Garden Netting

Netting can cause the hedgehog to get trapped, and complications may arise if it cuts off the hog’s blood supply.

Suddenly releasing the tension by cutting off the netting may cause further complications.

Prevent this accident by ensuring that the netting is stretched, anchored, and, if possible, elevated from the ground.


Slug Pellets

If a hedgehog consumes a slug contaminated with chemicals, it also runs the risk of being poisoned.

Of course, there is also the possibility of the hedgehog eating the pellet so try to use nontoxic alternatives to wildlife like Ferric Sodium EDTA or use slug traps instead.


Rat Poison and Traps

Traps attract not only the attention of rats but also juvenile hedgehogs looking to nest in these boxes that are dark, dry, and safe in the corner of the garden.

Recent studies show that most hogs analyzed post-mortem have rat poison in their stomach, so try to use other safe trap versions for wildlife.


Oil and Grease

Hedgehogs are not interested in oil or grease for food, but their curiosity may get them in trouble as these toxic materials can coat their bodies.

Tins of paint, oil cans, and other similar materials should always have a lid and be stored properly.


Plastic Holder

Hedgehogs may get trapped in plastic holders for beer or other drinks because their spikes hold them in place, and may die.

It is like any other animal that gets restricted and unable to move.

Reduce hedgehog injuries by cutting the plastic holders before throwing them in a recycling bin.


Open Food Cans

While trying to retrieve food from food cans or cups, they may enter the container head first and get stuck because of the quills.

Be resourceful and reuse or squash the cans before throwing them in a recycling bin.


Feeding While in the Wild

Some people try to help by feeding the wild hedgehogs, but they do not realize they may be causing harm as well.

Wet cat food usually comes in tin cans where hedgehogs may get stuck, milk causes diarrhea, and bread or cookies contain sugars but not enough nutrients.

Try to research what you can feed hedgehogs to supplement their natural diet.


Pools of Water

Hedgehogs are good swimmers but can eventually tire out and drown.

Garden ponds, swimming pools, and drains allow the hedgehog to fall through, but the steep and slippery sides will prevent them from getting out.

It is a good idea to place a plank of wood on pools and ponds which the hedgehog can climb and to cover drains with chicken wire.


Wrap Up

Although there are several threats to hedgehogs, we can still assure their existence by caring for them and their natural habitat.

Domesticated hedgehogs are becoming common pets, which means that other places may start to see a business in them.


Please only talk to certified breeders as they provide the proper care and are licensed (if applicable) to do so.


You can also take care of wild hedgehogs by providing them supplementary food, clean water, and a hog hut.

Watching them come and go through your garden can be just as enjoyable.

  • I have a chinchilla and I want a farm with five hedgehogs and other pets are a threat to them

    • Thank you for the information. I enjoy hearing anything that will help my domesticated HEDGIE live a more healthy lifestyle.

  • I have made tunnels under my back fence and also adjoining fences to enable hogs to find food. I am saddened to learn that these cute creatures face extinction very soon if we don’t help so hope everyone will do what they can.

    • Hi Annemarie, thanks for sharing this interesting positive action.
      Let’s hope that all breeders can provide with the right actions to avoid this to happen and that hedgehog pet owners also do what you have done for yours.

  • I would NOT put different species like this together in one common, enclosed area. Dietary needs are quite different and even if food items are put in separate dishes, their curiosity will make them want to sample the other items not suited for them. Certain zoonoses particular to, and not harmful to, one species may likely kill another. Chins do not like heat, whereas hedgehogs need heat. Also consider the potential for injury as well- if a chin drops jumps down onto a grassy or concealed area housing a hedgehog, it could get injured from the spikes. Different dietary needs, different environmental needs, different illnesses.
    Always do research to keep your pets safe.

    • Hi Mika,
      thanks for your valuable input.

  • I’m not going to buy a Hedgehog until I have everything I need and the time for her! It’s really important to devote time to your animals! They love you and always want to be with you! I have to make sure I’m not taking time away from my other animals! I also need to do lots of research so I can be a good Mama for the animal! I’m looking forward to this!

    • Hi Heather,
      thanks for putting them up first. Certainly they have to be treated well and having all necessary elements for them to live comfortably, is important.

  • hi, I would like to know

    1. if my hedgie can be placed from her cage and let her go in the garden to roam around under supervision or perhaps a fair size floorless playpen in order to feel something natural rather than just being her cage.

    2. When do I need to cover her cage with a blanket/towel during the day or night? She is in a warm place at home.

    Many thanks

    • Hi Sue, thanks for asking this questions.
      1- It is not a bad idea to give them that freedom. In fact, that will keep them more healthy as being in a small cage for all the time is not good for any pet. What ever you do, just make sure the hedgehog don’t find a small whole where can hide or disappear.
      2-Since they are more inactive during the day, and therefore sleep to recover the energy, it would be better at these hours.

  • I want a pet hedgie!
